Abstract:A numerical model is developed to investigate energy dissipations and residual stress distributions in friction stir welds. Results indicate that the maximum longitudinal residual stress can be increased with the increase of the translational velocity of the pin. But the variation of the angular velocity of the pin does not significantly affect the residual stress distributions. Energy dissipation in friction is increased with the increase of the angular velocity of the pin. However, with the increase of the translational velocity of the pin the plastic dissipation of energy is increased and the frictional dissipation is decreased.
